IMPROVEMENTIN PLOWS.

Specification forming part of Letters Patent No. 5,218, dated August 7,1847.

To all whom it may concern:

Be it known that I, GEORGE PAGE, of the city and county of Washington,and District of Columbia, have invented a new and useful Improvement inPlows; and I do hereby declare that the following is afull, clear, andexact description of the principle or character which distinguishes itfrom all other things before known, and of the manner of making,constructing, and using the same, reference being had to theaccompanyingdrawings, making part of thisspecification, in which.

Figure 1 is a side elevation of the mold-board side, and Fig. 2 is atear elevation.

The same letters indicate like parts in all the figures.

The nature of my improvement consists in supplying a revolving concavedisk inplace of the ordinary mold-board for turning the furrow, andadapting the other parts of the plow thereto.

In the accompanying drawings, a represents the handles of the plow, andb the beam. These are of ordinary construction, and are all connectedtogether. The lan'dside and share are also similar to some now in use.The cutter c is in one piece with the landside, and is thickened at itsback edge, and there has a recess,

cl, curved so as to lit the periphery of the revolving mold-board. Thismold-board m is attached to a holster, a, projecting from one side ofthe beam by a bolt through the center of the disk, on which it turns ason an axle. The bolster is shaped somewhat, to the back of the disk, andaids in supporting it. A frictionroller, r, sustains the pressureagainst the lower edge of the mold-board at the heel, having itshearings in adjustable projections from the landside, by which the heelof the moldboard can be set out orin. Another small friction-roller maybe placed in front of the disk at t, as shown by dotted lines, oppositethe beam. This is sustained by a curved brace,j, which is attached tothe beam in front of the mold-board. It curves out over the edge of themold-board, and then follows its curve on a line with its radii to thecenter, when it is bolted, and then terminates beyond in a spring, whichserves as a scraper to keep the moldboard clear.

What I claim as myinvention, and desire to secure by Letters Patent, is-

1. The employment of a concave circular revolving mold-board for a plow,constructed substantially in the manner and for the purpose set forth.

2. The outer brace and scraper, in combination with the above, for thepurposes set forth.

3. The employment of the friction-rollers, in combination with therevolving mold-board, substantially as above specified, for adjustingthe heel of the mold-board out or in to regulate the furrow.
